Description

Technical Field

[0001] This application relates to the field of sweeping and washing structure technology for sweeping and washing robots, and more particularly to an easily detachable roller structure and an intelligent sweeping and washing robot. Background Technology

[0002] With the development of intelligent technology, household intelligent cleaning robots have become an indispensable smart home device. These robots can automatically complete sweeping and mopping tasks, reducing the amount of housework for users. Typically, an intelligent cleaning robot consists of two main components: a main unit and a base station. The main unit performs simultaneous sweeping and mopping operations. When the main unit performs mopping, it generally uses a roller structure that is rotatably connected to a power source and to the bottom shell of the main unit. However, as usage time increases, the roller inevitably requires maintenance, cleaning, or replacement. Existing roller structures, in order to ensure connection stability, often suffer from inconvenient disassembly and assembly, increasing maintenance difficulty.

[0003] Therefore, how to improve the ease of assembly and disassembly of the roller structure while ensuring its connection stability has become an urgent technical problem to be solved. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an easy-to-disassemble roller structure and an intelligent sweeping robot, which aims to solve the problem of inconvenient disassembly and assembly of the roller of the main unit of the intelligent sweeping robot in the prior art.

[0005] The technical solution adopted by this application to solve the technical problem is as follows: an easily detachable roller structure for the main unit of an intelligent sweeping robot, comprising:

[0006] The main unit bottom shell has a roller groove provided along its length and a connecting end provided at one end of the roller groove along its length.

[0007] A roller assembly, one end of which is disposed in the roller groove, and the roller assembly and the roller groove are in clearance fit.

[0008] A roller lock is detachably connected to the connecting end and is connected to one end of the roller assembly.

[0009] In the above embodiments, by setting a roller lock in the easily detachable roller structure, and connecting one end of the roller lock to the roller assembly, and detachably connecting it to the connection end of the main unit bottom shell, the roller assembly can be fixed on the main unit bottom shell, and the roller lock can be used to easily detach and install the roller assembly on the main unit bottom shell, which is convenient for maintenance.

[0010] Optionally, the roller lock includes:

[0011] A lower cover for the roller assembly, one end of which is connected to the roller assembly.

[0012] A roller cover, wherein the roller cover is detachably connected to the end of the roller cover opposite to the roller assembly;

[0013] A handle fastener is provided between the lower cover of the roller and the upper cover of the roller, and both ends of the handle fastener along the width direction are engaged with the connecting end;

[0014] A roller handle is hinged to one end of the upper roller cover away from the lower roller cover, and is used to adjust the relative position of the handle fastener and the connecting end.

[0015] In the above embodiments, the lower roller cover is connected to the roller assembly to achieve the connection between the roller and the roller locking assembly. The upper roller cover is connected to the upper roller cover to support the handle fastener, the roller handle, and the roller assembly. The handle fastener enables a detachable connection with the main unit's bottom shell. By setting the roller handle, the relative positional relationship between the handle fastener and the main unit's bottom shell can be adjusted, thereby adjusting whether the roller locking is locked to the main unit's bottom shell, which facilitates the disassembly and assembly of the roller assembly.

[0016] Optionally, the handle fastener includes:

[0017] handle body;

[0018] A stop block is disposed on the end face of the fastener body facing the upper cover of the roller and extends out from the upper cover of the roller;

[0019] Locking teeth, wherein the locking teeth are disposed at one end of the fastener body along the width direction;

[0020] A latch is provided at the other end of the fastener body along the width direction.

[0021] In the above embodiment, the stop block is used to abut against the roller handle, thereby adjusting the relative position of the locking teeth and latches to the connection end of the main unit bottom shell, and thus controlling the locking and disengagement of the handle fastener to the main unit bottom shell. By setting the locking teeth and latches at both ends of the fastener body, the main unit bottom shell can be locked at two points, improving the stability of the connection. At the same time, the connection state of the locking teeth and latches to the main unit bottom shell can be controlled by linear displacement, which facilitates the easy assembly and disassembly of the roller assembly while maintaining connection stability.

[0022] Optionally, the main unit's bottom shell is provided with a snap-fit ​​hole and a buckle at the connection end. The snap-fit ​​hole and the buckle are arranged opposite each other along the width direction. The locking tooth is detachably connected to the snap-fit ​​hole, and the buckle is detachably connected to the buckle.

[0023] In the above embodiments, by setting the snap-fit ​​hole and the buckle, the locking tooth engages with the snap-fit ​​hole, and the locking buckle engages with the buckle. When the locking tooth disengages from the snap-fit ​​hole, the locking tooth disengages from the buckle and locks itself. This not only improves the connection stability between the handle fastener and the main unit's bottom shell, but also facilitates the disassembly and assembly of the roller assembly.

[0024] Optionally, the roller cover includes:

[0025] Top cover body;

[0026] A handle recess is provided at one end of the upper cover body that is away from the lower cover of the roller.

[0028] The fastener hole is located at the handle countersunk at the handle pivot, and the stop block extends out from the fastener hole.

[0029] In the above embodiments, by providing the fastener hole, the stop block of the handle fastener can extend out from the fastener hole, which facilitates the connection of the roller handle and the adjustment of the position of the handle fastener relative to the main body bottom shell by means of the roller handle; by providing the handle recess and the handle pivot, the roller handle is rotatably connected to the upper cover body, which facilitates the recessed assembly of the roller handle to the upper cover body and the operation of the locking state of the roller lock and the main body bottom shell.

[0030] Optionally, the roller handle includes:

[0031] The handle body includes a first end of the handle disposed along its width direction.

[0032] A pivot hole is provided at the first end of the handle and extends through the handle body along the height direction; the handle pivot is provided in the pivot hole.

[0033] A stop block clearance groove is provided at the position of the first end of the handle corresponding to the fastener hole;

[0034] A toggle block is provided at the first end of the handle corresponding to the fastener hole, and the toggle block and the stop block clearance groove are arranged adjacent to each other along the circumference of the pivot hole.

[0035] In the above embodiment, the handle body is rotatably connected to the upper cover body. By providing adjacent stop slots and actuating blocks on the handle body, the stop is accommodated in the stop slot when locked. When the handle body is rotated, the actuating block abuts against and pushes the stop, thereby adjusting the locking state of the handle fastener and the main unit bottom shell.

[0036] Optionally, the handle fastener further includes:

[0037] The first reset fixing member is disposed on the end face of the fastener body facing the upper cover of the roller;

[0038] A fastener reset component, one end of which is connected to the first reset fixing component;

[0039] The upper cover of the roller also includes a second reset fixing member, which is disposed on the end face of the upper cover body facing the lower cover of the roller, and the other end of the fastener reset member is connected to the second reset fixing member.

[0040] In the above embodiments, by setting a fastener reset component and setting a first reset fixing component and a second reset fixing component on the fastener body and the upper cover body respectively, the handle fastener can automatically reset and lock the main unit bottom shell under the action of the fastener reset component.

[0041] Optionally, the lower roller cover includes a roller bearing fixing hole, the handle fastener includes a roller bearing clearance groove, and the upper roller cover includes a roller bearing clearance portion disposed on the end face of the upper cover body facing the lower roller cover.

[0042] The roller assembly includes a locking connector and a roller body connected in sequence. The locking connector includes a bearing connector and a bearing that are fixedly connected. The roller body includes a cylinder and a roller brush sleeved on the cylinder. The bearing is fixed in the bearing fixing hole and accommodated in the roller bearing clearance groove and roller bearing clearance portion. The end face of the lower roller cover facing away from the upper roller cover is spaced apart from the bearing connector. The cylinder is provided with an axial cavity. Several transmission keys are arranged circumferentially and extending axially in the axial cavity. The bearing connector is accommodated at one end of the axial cavity and engages with the transmission keys.

[0043] In the above embodiment, by providing a roller bearing fixing hole on the drum roll cover, and setting the locking connector as a bearing connector and a bearing, and fixing the bearing in the roller bearing fixing hole, the roller body can rotate relative to the roller lock.

[0044] Optionally, the main unit bottom shell further includes a power end disposed opposite to the connecting end along the length direction; the roller assembly further includes a transmission connector disposed opposite to the locking connector, the transmission connector being housed at both ends of the shaft cavity and engaging with the transmission key;

[0045] The easily detachable roller structure also includes a roller power assembly located at the power end of the roller groove. The roller power assembly includes a motor, a transmission gearbox, and a roller output shaft. The motor is connected to the transmission gearbox, one end of the roller output shaft is connected to the transmission gearbox, and the other end of the roller output shaft is circumferentially engaged with the transmission connector.

[0046] In the above embodiments, a stable rotational transmission of the roller is achieved by setting up a roller power assembly.

[0062] Please refer to the following: Figures 1 to 3The first embodiment of this application provides an easily detachable roller structure 20, which is used in the main unit of an intelligent sweeping robot and mainly serves as the mopping function structure of the main unit. Specifically, the easily detachable roller structure 20 includes: a main unit bottom shell 21, a roller assembly 22, and a roller lock 23. The main unit bottom shell 21 has a roller groove 210 along its length and a connecting end 211 located at one end of the roller groove 210 along its length. One end of the roller assembly 22 is located in the roller groove 210, and the roller assembly 22 and the roller groove 210 are in clearance fit. That is, the roller assembly 22 is fitted into the roller groove 210, and the groove wall of the roller groove 210 is provided with a fitting clearance, thereby ensuring... The roller assembly 22 rotates relative to the main unit bottom shell 21 to complete the mopping operation. The roller latch 23 is detachably connected to the connecting end 211, and the roller latch 23 is connected to one end of the roller assembly 22. It can be seen that the roller assembly 22 is connected to the main unit bottom shell 21 through the roller latch 23. This can be achieved by operating the roller latch 23. In other words, by setting the roller latch 23 in the easy-to-disassemble roller structure 20, and connecting one end of the roller latch 23 to the roller assembly 22, and detachably connecting it to the connecting end 211 of the main unit bottom shell 21, the roller assembly 22 can be fixed to the main unit bottom shell 21, and the roller latch 23 can be used to easily disassemble and install the roller assembly 22 on the main unit bottom shell 21, which is convenient for maintenance.

[0063] Please refer to the following: Figures 4 to 5In some embodiments, the roller lock 23 includes: a lower roller cover 231, an upper roller cover 232, a handle fastener 233, and a roller handle 234; one end of the lower roller cover 231 is connected to the roller assembly 22. Specifically, the roller assembly 22 is axially fixedly connected to one end of the lower roller cover 231, and circumferentially rotatably connected to the lower roller cover 231, thereby preventing the roller assembly 22 from detaching from the roller groove 210 axially and ensuring the normal operation of the roller assembly 22; the upper roller cover 232 is detachably connected to the end of the lower roller cover 231 opposite to the roller assembly 22; the handle fastener 233 is disposed on the lower roller cover 231 and the upper roller cover 234. Between 32, and both ends of the handle fastener 233 along the width direction are engaged with the connecting end 211. That is, the roller lock 23 is connected to the main body bottom shell 21 through the handle fastener 233. The handle fastener 233 is disposed between the upper roller cover 232 and the lower roller cover 231. The roller assembly 22 is connected to the lower roller cover 231. The handle fastener 233 is connected to the main body bottom shell 21. The roller handle 234 is hinged to the end of the upper roller cover 232 away from the lower roller cover 231. That is, the roller handle 234 can rotate relative to the upper roller cover 232. The relative position of the handle fastener 233 and the connecting end 211 can be adjusted by the roller handle 234.

[0064] In other words, the roller assembly 22 is connected to the roller lower cover 231, thereby connecting the roller assembly 22 with the roller lock 23. The roller upper cover 232 is connected to support the handle fastener 233, the roller handle 234, and the roller assembly 22. The handle fastener 233 enables a detachable connection with the main unit bottom shell 21. By setting the roller handle 234, the relative positional relationship between the handle fastener 233 and the main unit bottom shell 21 can be adjusted, thereby adjusting whether the roller lock 23 is locked to the main unit bottom shell 21, which facilitates the disassembly and assembly of the roller assembly 22.

[0065] In some embodiments, the handle fastener 233 includes: a fastener body 2331, a stop block 2332, a locking tooth 2333, and a locking buckle 2334; the stop block 2332 is disposed on the end face of the fastener body 2331 facing the upper roller cover 232 and extends from the upper roller cover 232, indicating that the stop block 2332 protrudes from the end face of the upper roller cover 232 away from the lower roller cover 231, thereby facilitating intermittent contact between the roller and the roller handle 234; the locking tooth 2333 is disposed at one end of the fastener body 2331 along the width direction; the locking buckle 2334 is disposed at the other end of the fastener body 2331 along the width direction.

[0066] In other words, the stop block 2332 is used to abut against the roller handle 234, thereby adjusting the relative position of the locking teeth 2333 and the latch 2334 with the connection end 211 of the main body bottom shell 21, thereby controlling the locking and disengagement of the handle fastener 233 with the main body bottom shell 21. By setting the locking teeth 2333 and the latch 2334 at both ends of the fastener body 2331, the main body bottom shell 21 can be locked at two points, improving the stability of the connection. At the same time, the connection state of the locking teeth 2333 and the latch 2334 with the main body bottom shell 21 can be controlled by linear displacement, which facilitates the easy assembly and disassembly of the roller assembly 22 while maintaining connection stability.

[0067] Please refer to the following: Figures 4 to 7 In some embodiments, the main unit bottom shell 21 is provided with a snap-fit ​​hole 212 and a buckle 213 at the connection end 211. The snap-fit ​​hole 212 and the buckle 213 are arranged opposite to each other in the width direction. The locking tooth 2333 is detachably connected to the snap-fit ​​hole 212, and the buckle 2334 is detachably connected to the buckle 213.

[0068] It is understood that the snap-fit ​​hole 212 engages with the locking tooth 2333, and the latch 2334 engages with the latch 213. That is, both ends of the handle fastener 233 along the width direction are connected to the main unit bottom shell 21, thereby forming an axial limit on the roller assembly 22. At the same time, the snap-fit ​​hole 212 can limit one end of the roller assembly 22 in the width direction. To disassemble, it is only necessary to move the roller handle 234, which pushes the stop block 2332, causing the fastener body 2331 to move horizontally along the width direction, so that the locking tooth 2333 disengages from the latch, and the latch 2334 disengages from the latch 213, thereby releasing the locking state of the handle fastener 233 and the main unit bottom shell 21, and thus facilitating the disassembly of the roller assembly 22. That is, by setting the snap-fit ​​hole 212 and the buckle 213, the locking tooth 2333 is snapped into the snap-fit ​​hole 212, and the buckle 2334 is snapped into the buckle 213. When the locking tooth 2333 disengages from the snap-fit ​​hole 212, the locking tooth 2333 disengages from the buckle 213. This not only improves the connection stability between the handle fastener 233 and the main unit bottom shell 21, but also facilitates the disassembly and assembly of the roller assembly 22.

[0069] Please refer to the following: Figures 4 to 5In some embodiments, the upper cover 232 of the roller includes: an upper cover body 2321, a handle recess 2322, a handle pivot 2323, and a fastener hole 2324; the handle recess 2322 is disposed at one end of the upper cover body 2321 away from the lower cover 231 of the roller; the handle pivot 2323 is disposed on the upper cover body 2321 on both sides of the handle recess 2322, and the handle fastener 233 is rotatably connected to the handle pivot 2323; the fastener hole 2324 is disposed at the handle recess 2322 at the handle pivot 2323, and the stop block 2332 extends out from the fastener hole 2324. It is understood that by setting the fastener hole 2324, the stop block 2332 of the handle fastener 233 can extend out of the fastener hole 2324, which facilitates the connection of the roller handle 234 and the adjustment of the position of the handle fastener 233 relative to the main body bottom shell 21 by means of the roller handle 234; by setting the handle recess 2322 and the handle pivot 2323, the roller handle 234 is rotatably connected to the upper cover body 2321, which facilitates the recessed assembly of the roller handle 234 onto the upper cover body 2321, and the roller handle 234 will not protrude relative to the upper cover body 2321, and also facilitates the operation of the locking state of the roller lock 23 and the main body bottom shell 21.

[0070] Please refer to the following: Figures 4 to 5In some embodiments, the roller handle 234 includes: a handle body 2341, a pivot hole 2342, a stop block recess 2343, and a toggle block 2344; the handle body 2341 includes a first handle end 2345 disposed along the width direction; the pivot hole 2342 is disposed at the first handle end 2345 and extends through the handle body 2341 along the height direction, and the handle pivot 2323 is disposed in the pivot hole 2342; the stop block recess 2343 is disposed at the position of the first handle end 2345 corresponding to the fastener hole 2324, indicating that the stop block 2332 extends from the fastener hole 2324. After extending, it is accommodated in the stop block recess 2343; the actuating block 2344 is disposed at the position of the first end 2345 of the handle corresponding to the fastener hole 2324, and the actuating block 2344 and the stop block recess 2343 are arranged adjacent to each other along the circumference of the pivot hole 2342. It can be seen that when the handle body 2341 is moved, the relative position of the stop block recess 2343 and the actuating block 2344 changes, and the actuating block 2344 abuts against the stop block 2332 at a specific angle, pushing the handle body 2341 to move, thereby adjusting the locking state of the locking teeth 2333 and the latch 2334 with the main unit bottom shell 21. In other words, the handle body 2341 is rotatably connected to the upper cover body 2321. By setting adjacent stop slots 2343 and actuating blocks 2344 on the handle body 2341, the stop block 2332 is accommodated in the stop slot 2343 when locked. When the handle body 2341 is rotated, the actuating block 2344 abuts against and pushes the stop block 2332, thereby adjusting the locking state of the handle fastener 233 and the main unit bottom shell 21.

[0071] Please refer to the following: Figures 4 to 5 In some embodiments, the handle fastener 233 further includes: a first reset fixing member 2335 and a fastener reset member 2336; the first reset fixing member 2335 is disposed on the end face of the fastener body 2331 facing the upper roller cover 232; the upper roller cover 232 further includes a second reset fixing member 2325, the second reset fixing member 2325 is disposed on the end face of the upper cover body 2321 facing the lower roller cover 231, and the other end of the fastener reset member 2336 is connected to the second reset fixing member 2325.

[0072] It is understood that by setting a fastener reset component 2336, and setting a first reset fixing component 2335 and a second reset fixing component 2325 on the fastener body 2331 and the upper cover body 2321 respectively, the handle fastener 233 can automatically reset and lock the main unit bottom shell 21 under the action of the fastener reset component 2336.

[0073] Please refer to the following: Figure 2 , Figure 4 , Figure 5 and Figure 8 In some embodiments, the lower roller cover 231 includes a roller bearing fixing hole 2311, the handle fastener 233 includes a roller bearing clearance groove 2337, and the upper roller cover 232 includes a roller bearing clearance portion 2326 disposed on the end face of the upper cover body 2321 facing the lower roller cover 231; the roller assembly 22 includes a locking connector 221 and a roller body 222 connected in sequence, the locking connector 221 includes a bearing connector 2211 and a bearing 2212 fixedly connected, the roller body 222 includes a cylinder 2221 and a roller brush 2222 sleeved on the cylinder 2221; the bearing 2212 is fixed in the bearing 2212 fixing hole and accommodated in the roller bearing clearance groove 2337 and the roller bearing clearance portion 2326, and the bearing 2212 and the roller body 222 are axially limited, and the lower roller cover 231... The end face of the roller cover 232 facing away from the bearing connector 2211 is spaced apart, meaning the roller cover 231 does not contact the bearing connector 2211, thus preventing the roller cover 231 from interfering with the rotation of the bearing connector 2211 and the roller. The cylinder 2221 is provided with an axial cavity 2223, in which a plurality of transmission keys 2224 are arranged circumferentially and extended axially. That is, the plurality of transmission keys 2224 are all extended axially and are evenly spaced circumferentially. The bearing connector 2211 is housed at one end of the axial cavity 2223 and engages with the transmission keys 2224.
